Epic PFP LB LC Columns - 50 mm, 2.1 mm I.D., 1.8 μm

The Epic PFP LB (low bleed) is a pentafluorophenyl that has been baseline stabilized and is ready for high performance separations. The Epic PFP LB is a truly unique stationary phase with properties significantly different than C18 phases. This unique characteristic results from bonded pentafluorophenyl groups imparting a π-π electron interaction which produces an enhanced retention for many compounds, such as natural products, halogenated compounds, aromatics, conjugated compounds and trace impurities in complex matrices. Many of these high-performance separations were not possible with existing PFP columns especially in the area of trace impurities where baseline bleed levels were unacceptable. Epic PFP LB columns have been stabilized to provide low column bleed, increased lifetimes, better pH stability, and superior LC-MS performance.

Application Brief

HPLC Analysis of Lamotrigine Related Compound B Impurity in Accordance with the USP Application Brief

Lamotrigine is an antiepileptic drug belonging in the phenyl triazine class. It is used in the treatment of both epilepsy and as a mood stabilizer for bipolar disorder. Lamotrigine related compound B also known as 2,3-dichlorobenzoic acid is a key intermediate for the antiepileptic drug Lamotrigine. It may be in found in the final product and needs to be monitored and controlled over the shelf life of the product.

The methods for assessing Lamotrigine related compound B are described in the United States Pharmacopeia1 and rely on chromatographic techniques. This application brief describes use of an Epic C18 column coupled with the LC 300 liquid chromatography system and SimplicityChrom chromatography data system (CDS).

HPLC and UHPLC Column Portfolio Interactive Brochure

Every decision you make in the lab affects your scientific outcomes – and that holds true for column choices. Sample solubility, chemical differences among analytes, and stationary phase chemistry are key factors in deciding which column is right for your application. The column vendor you choose must deliver the reliability, scalability, and reproducibility you need to get the most value from your method-development, quality-control, and preparative-purification processes.

Our innovative, highly efficient HPLC/UHPLC and supercritical fluid chromatography (SFC) column chemistries from ES Industries (now a PerkinElmer company) provide scientists like you with the highest quality columns, including novel chiral and achiral fluorinated phases specifically designed with pharmaceutical and environmental applications in mind. Building on ES Industries’ 40 years’ experience in column technology, we support you with applications assistance, method development guidance, and column recommendations, too.
